Metal casting for production-quality prototypes
We offer three metal casting processes to meet your prototyping needs: the sand casting process, the investment casting process and the rubber plaster molding process. Because each metal casting process has its strengths, we can recommend the one that will best achieve your objectives.
Sand Casting Process
Moist-bonded or resin-coated sand is packed tightly around a pattern. The pattern is removed, and the molten metal is poured into the corresponding cavity. The sand casting process is one of the most affordable methods of creating a metal casting.
Investment Casting Process
This process is known as lost-wax casting because the wax pattern is "lost" when the ceramic shell is heated. Investment casting can produce parts with intricate geometries easily with a high rate of repeatability for either short or long runs.
Rubber Plaster Molding Process
From the pattern, a silicone rubber mold is created, from which a urethane positive is cast. Liquid plaster slurry is created from the urethane pattern and then baked. Then the metal is poured. This process generates parts with finely detailed surface finishes.
